LOGGING BUNK.

Application filed May 18,

My invention relates primarily to a bunk for use in transporting logs by railway from the woods to the mills, although it is not limited to such specific use and may be used upon motor trucks and the like for shipping pipe and other similar tubular or cylindrical material, and the prime object thereof is to provide a logging'bunk which, while providing the maximum security for the materials during transportation and the maximum safety for the operator while the logs or the like are being unloaded, will be simple in construction and operation and cheap to manufacture.

Another object is to provide a device of the above character which is equally applicable tonew or old cars or vehicles and which can be easily and quickly mounted thereon without materially altering the same.

Other objects and advantages will appear hereinafter and, while I have shown and will describe the preferred form of my invention, it will be understood that I do not limit myself to such preferred form but that various changes and adaptations may be made therein withoutdeparting ai 1:011] the spirit of my invention.

In the drawings accompanying and forming a part hereof:

Fig. 1 is a side elevation of my bunk detached from its place of use.

Fig. 2 is a top plan of Fig. 1, partly broken away.

Fig. 3 is a right hand elevation of Fig. 1.

Fig. 4 is a fragmentary side elevation of my bunk showing the method of releasing the blocks.

Fig. 5 is a fragmentary side elevation showing the position of the block after being released.

Referring to the drawings my bunk comprises a' base 6, preferably of wood upon the upper face of which is mounted a channel member 7 by means of bolts 8 or otherwise. Formed in each end of base 6, centrally thereof, are recesses 9 and 10, which register with similar recesses 11 and 12 in the ends of channel member 7 A saddle 13 surrounds the lower ends of each of the recesses 9 and and is secured to base 6 by bolts 14 and forms a socket for the reception of the lower end of the holding blocks 15. Blocks 15 have their upper major portion of a width corresponding to the width of the channel member 7 and their lower ends are sized to snugly fit the recesses 9 1926. Serial No. 109,871.

members 22 and 23. Members 22 and 23 are I substantially L-shaped in top plan and pintles and 21 pass through one of the legs thereof about centrally of their length. The pivoted leg of members 22 and 23 roject from opposite sides of base 6 and t e free ends terminate in apertured bosses 24 and 25.

The other ends of members 22 and 23 are connected to operating levers 26 and 27 which normally lie parallel with the sides of said base and extend therealong to the opposite end of base 6. Blocks 15 are connected to base 6 by short chains 28 and 29 which serve to retain the same against displacement or loss. Secured at one end to the sides of base 6 at the ends thereof and on opposite sides of said base are holding chains 30 and 31. Extending outwardly from opposite sides of base 6 just below the outer termination of the elongated openings 18 and 19 are eye bolts 32 and 33 and mounted at one end upon the eyes are the locking hooks 34 and 35 adapted in cooperation with the apertured bosses 24 and 25 to lock the free ends of chains 30 and 31 to base 6 to hold blocks 15 in their operative positions. Secured at one end to the side of base 6 near the ends thereof are chains 36 and 37 adapted to be brought to surround the free ends of operating levers 26 and 27 and have their free ends detachably mounted upon hooks 38 and 39 to secure said levers against movement.

In the o eration of my bunk, it bein understood tiiat a car or other vehicle will be equipped with a bunk at each end and sometimes intermediate the ends, depending upon the length oi the car and the length of the material it is intended to handle, the parts willnormally lie in the position shown in Figs. 1, 2 and 3. It will be noted that the holding chains 30 and 31 extend from their connection to base 6 around the outer Sides of blocks 15 and over. hooks 16 and 17 and the free ends are then engaged by the looking hooks 34 and 35, the free ends of these hooks being positioned within the apertured bosses 24 and 25. v

lVhen it is desired to unload the load from the car or vehicle the operator will take his position at the opposite side of the car from which it is desired to unload. He will then release the chains 26 or 27 and move the respective operating handle outwardly away from the side of base 6, which will rock members 22 and 23 and move the apertured boss from engagement with the end of locking hooks 34 and 35. The pressure of the load will then force the upper end of block 15 outwardly withdrawing the end of the holding chain from hook 34 or 35. Continued pressure of the load upon block 15 will upset the same withdrawing the lower end thereof from the saddle 13 and it will then fall to the limit of the short chains 28 or 29 out of the way of the falling logs.

By this construction I have provided a simple and very eilicient logging bunk in which the danger of injury to the workman is entirely eliminated due to the factthat the blocks or stakes are released from the side of the car opposite to that at which the stake is located and the load dumped off.

Having described my'invention what I claim is:

1. In combination with a railway flat car a logging bunk therefor comprising a rectangular base mounted upon said car at the end thereof; a' substantially U-shaped channel member mounted upon said base to open upwardly, a recess in each end of said base and channel member centrally of the width thereof; a saddle surrounding the lower end of said recess and forming a socket; elongated apertures passing through said base horizontally and transversely thereof; substantially L-shaped securing members 'pivotally mounted centrally of the length of one of their legs in said apertures, the free end .of said pivoted legs terminatin in apertured -bosses; operating levers secure at one end to the other leg, of said securing members to normally lie parallel with said ivotally connected at one end to the side'oi said base in juxtaposition to said apertured bosses adapted to co-operate therewith to secure the free ends of said locking chains in operative positions; a holding block loosely secured to the end of said'base ada ted to be mounted at its lower end in sai recess and socket and be held positioned therein b said holding chain adapted when said c ain is released to fall from said socket and recess upon pressure from the load; and means to secure said operating handle against movement.

2. In combination with a railway flat car, a lo ging bunk therefor comprising a rectangu ar base mounted upon each end thereof to extend transversely; a substantially U-shaped channel member mounted on said base 0 ening upwardly a recess in each end of sai base and channel member centrally of the width thereof a saddle surrounding and enclosing the lower end of said recess and forming a socket; elongated apertures passing transversely through said base horizontally thereof; securing members ivotallymounted in said apertures and roecting from each side of said base, sai so; curing members being substantially L-shaped in top lan and being mounted reversely to each ot er the free end being pivoted centrally of the length of one leg, the free end of said leg terminating in an aoertured boss, the other leg extending parallel with said base; securing hooks mounted on said base adapted to have the free end thereof projecting into said apertured boss;- holding blocks removably mounted in the recesses in the ends of said base and channel member and projecting above the same, the upper end of said blocks being of a width substantially equal to the width of said channel member and supported thereby; upwardly opening hooks secured to the outer face of each of said blocks; securing chains connected at one end to the sides of said base adapted to be passed around the outer face of said blocks within said hooks and have the free ends en aged by said securing hooks; operating handles connected to the other leg of each of said securing hooks for operating the same; and means to lock said operating levers against outward movement.

3. In combination a railway flat car, a bunk therefor comprising a rectangular base mounted at each end thereof to extend transversely its entire width; an upwardly opening channel member mounted u on said base in substantial register therewit a recess formed in the ends of said base and channel member; a saddle surrounding and closing the open side of said recess at the lower end thereof and forming a socket; a holding block mounted in each of said sockets to extend vertically above said base and channel, the lower end of said blocks being narrower than the upper end whereby supporting shoulders are formed to rest upon the upper face of said channel; an upwardly opening hook extending from the outer face of each of said blocks" elongated apertures extending through sai base near eachend transversely thereof and on a horizontal plane; substantially L-shaped securing members pivotally mounted centrally of the length of one vof their le s in said apertures to project from each si e of said base, the free end of said legs terminating in apertured bosses; securing hooks loosel mount ed upon thesides of said base a apted .to i

have their free ends engageable with'theapertures in said bosses; holding chains segamma cured at one end to the sides of said hase near each end thereof on the side opposite.

said apertured bosses adapted to he assed around the outer faces of said holding locks supported by said upwardly Opening hooks and have their free ends engaged by said securing hooks; operatin handles connected to the other 1e" of s'ai securing members for rocking said members on their pivots to withdraw said bosses from engagement with W said holding chains; and means for locking said operating handles against accidental movement.

In Witness that I claim the foregoing I have hereunto set my hand this 21st day of M'- August, 1925.
